59 Figure 8 is a ragment'al sectionalr view Angiilarlydisposed bracing beams 18 100 have their upper ends connected to the uprights 14, and have their lower ends connected to the bars l() as at 19, whereby the uprights 14 are further supported and held in their upright positions, with respect to the bars 10.

The boom support is in the form of a swinging frame embodying uprights 20 spaced apart, the lower ends thereof, being secured to the swinging base 21 carrying the pivot pin 22 that extends through a suitable opening in the bases 5 and 8. The uprights 2() are connected to the base 21 as clearly shown by Figure 1 of the drawings. A winch 23 is also positioned on the swinging base 21 to counterbalance the action of the weight of the load supported by the boom, and operates the flexible member.

The upper ends of the uprights 14 are connected by means of the bar 24, which bar supports the pivot pin 25 that extends through a suitable opening in the capping bar 16, so that the frame may pivot in a horizontal plane permitting the shovel to be moved to various angles with respect to the bases 5 and 8. Pivotally connected to the base 21 is a boom embodying spaced bars 26, which have ltheir upper ends connected as by means of the member 27 to which the pulleys 28 are connected. The pulleys 29 which are connected to the opposite sides of the boom accommodate the flexible c members 30 which also'move over the pulthe forward bar 15, as

le 7s 31 su orted b pp lligure 1 of the drawl Y of the invention includes a supporting arm 32 which is formed with side members providing a chute or trough to direct material dislodged by the shovel or scoop 33 to the receiving trough 34 supported at the rear end of the arm 32. This supporting arm 32 is hingedly supported by means of the swinging frame as by means of the supporting member 35, the rear end of the supporting arm 32 extending an appreciable distance beyond the uprights 14 where the same overlies the receiving trough 34 to discharge material thereinto.

The scoop or shovel, which is pivotally connected to the outer end of the arm 32 has upwardly extended arms 36 that support pulleys 37 over which the flexible connecting member 38 operates, the flexible connecting member 38 also moving over the pulleys 28 where the same extends to a point adjacent to the base 21 and passes over the drum not shown, of the winch 23.

The flexible member 30 also extends downwardly and isv positioned over a suitable drum forming a part of the motor controlled winch 23. Supported at one side of the arm 32 is a weight controlled latch member 39 that cooperates with the lug 40 carried by the scoop or bucket 33, which latch member is designed to hold the scoop 33 in a carrying position, when the arm and boom have been moved upwardly, thereby preventing the scoope 33 from discharging its contents prior to the movement of the same to a discharging position. A controlling rope 41 has connection with the latch member 39 and is adapted to be operated at a predetermined period to release the scoop and permit the sameto discharge its contents into the arm V32 or trough.

The receiving trough 34 is provided with an auxiliary bottom 42 which is formed with openings 43 that are covered by the screening elements 44, whereby the trough is divided into an upper compartment and a lower compartment, the heavier or larger stones passingthrough the upper compartment where they are discharged into a suitable receiver, while the finer grade of stone or material passes from the lower compartment into a suitable receiving member placed thereunder. l

A platform indicated at overlies the bars 10, and affords means to permit wagons to be driven under the receiving chute to receive material therefrom.

While I have shown and described the invention as a machine especially designed as a scoop shovel for digging trenches, ditches or the like, it is to be understood that by The pile driving guide is relatively long and includes opposed sections 46 and 47, which sections are connected as by means of the bolts 48 so that the sections may be disconnected and the driving medium, which is in the form of an elongated weight, placed therein.` The pulley 17 accommodates the flexible member 49 that has connection with the driving element not shown, the flexible member 49fmoving over the pulley and having its lower .end connected to a suitable drum carried by the winch 23 or power device. f

Having thus described the invention, what is claimed as new is An excavating machine including a stationary base, a rotatable base mounted at one end of the stationary base, a guide member secured to the stationary base and having a right angled end adapted to overlie a portion of the rotatable base, uprights carried by the rotatable base and having a pulley mounted adjacent to the upper end thereof, spaced bars mounted on the rotatable base and adapted to swing vertically. a scoop supporting arm pivotally mounted between the uprights and adapted to swing vertically, a flexible member having connection with the spaced bars for moving them vertically, a scoop on the scoop sup porting arm, a flexible member connecting:r

the scoop and the upper end of the vertically swinging' bars for adjusting the scoop with respect to the swinging bars, and a flexible men'iber for connecting' the vertically swinging,- bars to the uprights 'for adjusting the vertically swingingr bars and scoop with re- 10 spect to the uprights.

In testimony that I claim the foregoing as my own, I have hereto aiiixed my signature in the presence of two Witnesses.
